JOHN H. LAWRENCE, OF STERLING, ILLINOIS,ASSIGNOR OF ONE-HALF TO EDWIN F.LAWRENCE, OF SAME PLACE.

TRACK FOR BARN-DOORS.

SPECIFICATION forming part of Letters Patent No. 480,501, dated August9, 1892.

Application filed January 16, 1892. Serial No. 418,290- (No model.)

To all whom it may concern.-

Be it known that I, JOHN H. LAWRENCE, a citizen of the United States,residing at Sterling, in the county of Whiteside and State ofIllinois,have invented certain new and useful Improvements in Tracks forBarn-Doors; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

My invention has reference to improvements in barn-door tracks, ashereinafter more specifically described and claimed.

The purpose and object of my invention are to dispense with thenecessity of attaching the track to the bracket, as is usuallynecessary. In the ordinary constructions, by reason of the great weightof the suspended door, as many as nine attachments of the bracket to thetrack are required in an eight-foot track, each of which attachmentsnecessitates the forming of rivet-holes and the labor and expense ofseating rivets therein, with the result that the attachment whencompleted is not so solid and substantial as though themutually-attached parts were integral.

As my brackets can be forged into the required shape at the outset,there remains nothing further to be done in applying them to use thansimply fastening the back or upper end of the bracket to the mainbuilding.

The object of my invention can be subserved by brackets of differentform in crosssection-as, for instance, it may be extended upward abovethe crest of the roller and its attachments and projected outwardly fromthe building and slightly downward at its free upper end, so as to forma hood over the hanger to protect the latter from rain or snow; but thisaddition is merely supplemental to the main idea.

In the drawings, Figure l is a vertical crosssection of a bracketexhibiting my'invention and shown in position of attachment and use.Fig. 2isa perspective of the same. Fig.3 isa vertical cross-section ofthe bracket extended upwardly and outwardly to form a protection to thehanger, showing the roller in position for use.

A represents the side ofthe building to which the upper side of thebracket is attached.

B is the bracket, consisting of an upper portion C, adapted to lievertically against the outside of the building A and be attached to thelatter by a sufficient number of screws inserted at desired intervalsthrough the part Cinto the building.

D is the central diagonally-downward projecting portion of the bracketB, which is of sufficient length to place the roller-track E asufficient distance from the building to permit the ready passage of theroller and its attachments. The track E is thrown vertically upward fromthe outer and horizontal portion F of the bracket B, and such horizontalportion is extended a sufficient distance on each side of the track E toform the treads G Gfor the door-rollers. It is obvious that the track Emay also be utilized for that species of rollers which are supportedperipherally between the annular projections, which extend beyond thebearing-surface of the roller, and, by passing, respectively, down thesides of the track E, serve as guards for keeping the roller on thetrack.

In order to stiffen the bracket B and to assist in supporting the trackE against the imposed burden of the door, I interpose be tween thediagonal portion D of said bracket and the side of the building belowthe point of attachment thereto of said bracket triangular braces H,which are placed at such frequency as the weight of the door and theresisting quality of the bracket may make desirable. The triangularbrace H is preferably formed out of the central portion of the bracket Bby being cut out of the latter at its rear and lower edges, leaving itsdiagonal upper surface or the hypotenuse integral with the bracket B,whereby the expense of attaching the brace II either to the building orto the bracket 13 is avoided, and the braces H are always in place onsuch bracket and require no attachment other than that of the upperportion C of said bracket to the building. The openings in part D,created by cutting braces H therefrom, extend sufliciently low to drainany accumulations of water from behind track E.

\VhatI claim as myinvention, and desire to secure by Letters Patent ofthe United States, is-

1. In a track for supporting barn-doorrollers, a continuous bracket B,provided with the upper vertical portion C, adapted to be attached tothe building, the intermediate diagonal portion D, the track E, and thetriangular braces H, cut from the portion D, with their upper sidesintegral with the latter and their residue turned downward into aVertical position, with the inner ends of their severed portion in thevertical plane of the rear face of the portion 0, whereby said bracketis adapted to hang in proper position from the mere attachment, asaforesaid, of its portion C, for the purpose specified.

. 2. In a track for supporting barn-door roliers, the combination of avertical portion 0, adapted to be attached to the building and extendedupward and outward from the building to form a cover for thedoor-rollers, an intermediate diagonal portion D, a horizontal portionF, the track E, formed thereon, and triangular braces H, formed atsuitable intervals in the diagonal portion D, with their v severalhypotenuses integral with the portion D and their residue turneddownward therefrom into a vertical position, with their short verticalrear ends in substantially the same vertical plane with the back side ofthe portion 0 and adapted to rest against the building when the portion0 is attached to the latter,

and thereby support the track E a sufficient distance from saidbuilding, substantially as shown, and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN H. LAWRENCE.
